Oh yes, and we are to understand that they were left there by "workers." Like mechanics or cleaning crew, I guess. Lord knows how many boxes those people open in a day. Never met a mech who didn't have at least two boxcutters.
I have a good friend that found a boxcutter in a major airline cockpit last month. It was whisked away and he was told it was left there by maintenance. His follow-up emails to management were not answered.
Suck in your guts, people. I suspect the worst is coming, again....
